Grid computing deals with the effective utilization of the globally distributed computer resources to solve large problems. Effective scheduling algorithms are used for the effective utilization of the unused CPU cycles that are distributed geographically. The existing algorithms mainly focus on system performance rather than the user satisfaction. In this

A new Economic resource allocation model has been designed, that is efficient enough to allocate resource. Current existing economic resource allocation model has been criticized for their performance limitations and high overheads. This paper addresses the poor performance of current economic allocation models, by reducing the failure rate, reallocation rate,

Based on the analysis and distribution of network attacks in KDDCup99 dataset and real time traffic, this paper proposes a design of multi stage filter which is an efficient and effective approach in dealing with various categories of attacks in networks. The first stage of the filter is designed using

A Wireless Sensor Network (WSN) consists of spatially distributed autonomous sensors to monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants and to cooperatively pass their data through the network to a main location. There is a growing interest in the wireless sensor network technology

Pushback is a mechanism for defending against Distributed Denial-of-Service (DDoS) attacks. DDoS attacks are treated as a congestion-control problem, but because most such congestion is caused by malicious hosts not obeying traditional end-to-end congestion control, the problem must be handled by the routers. Functionality is added to each router to

In 3G mobile terminals the Viterbi decoder consumes approximately one third of the power consumption of a base band mobile transceiver. Viterbi decoders employed in digital wireless communications are complex and dissipate large power. In this paper, to reduce the power consumption, and to increase the speed, an asynchronous technique
